After reading your original post...I have a question. Was your old keyboard the same type of keyboard as you just purchased (both are the slim aluminum keyboard with the white "chicklet" keys)?

If both keyboards are the same design...are the function keys laid out exactly the same way?

Did all the function keys on the old keyboard work fine?

Nick. Apple DID cut out 10.5 and even some machines on newer versions of the USB keyboard with Numeric keypad. It was discussed here at one point. Will try and find the URL. I feel it's not fair. It's a keyboard! Keyboards should work on all machines. Grin
